How do you calculate concrete in a circle?
Calculator Use
- Choose Round Column (or Round Slab) on the calculator.
- Enter Height 4 ft (or 48 in)
- Enter Diameter 10 in.
- Calculate and the answer is 0.08 cubic yards for one concrete tube.
- Multiply 0.08 x 50 = 4 total cubic yards of concrete for 50 tubes.
What are all the formulas for a circle?
We use the circle formula to calculate the area, diameter, and circumference of a circle. The length between any point on the circle and its center is known as its radius….Formulas Related to Circles.
| Diameter of a Circle | D = 2 × r |
|---|---|
| Circumference of a Circle | C = 2 × π × r |
| Area of a Circle | A = π × r2 |

What is cubic footage in math?
Cubic footage is the measure of the volume of a space in cubic feet. To find the cubic footage of a cylinder, use the following formula: volume = π × r2 × h. The volume of a cylinder in cubic feet is equal to π times the radius in feet squared times the height in feet. π is roughly equal to 3.14159265359.
What is the volume of a cylinder in cubic feet?
The volume of a cylinder in cubic feet is equal to π times the radius in feet squared times the height in feet. π is roughly equal to 3.14159265359. If you know the diameter of the cylinder, you can find the radius by dividing the diameter by two, or just use our circle diameter calculator .
